4 Digital Scroll Compressor Modulation chamber Bleed hole Lift piston assembly Solenoid Spring The Digital Scroll Compressor uses a simple and effective method to modulate the capacity of an AC, giving unparalleled performance in the modulation field. To modulate the capacity the Digital Scroll operates in two stages, the loaded state in which the compressor works as a normal Scroll compressor at full capacity and mass flow, and the unloaded state, where there is not capacity and mass flow. During the unloaded state there is a separation between the scrolls. Once the scrolls separate, any gas passing through is no longer compressed. Changing the cycle time ( Loaded state time and Unloaded state time) determines the capacity modulation of the compressor. System Diagram Compact version The HVS-system is available as a COMPACT version. This version is particularly designed for process cooling applications for very low brine-temperatures (down to -5 C) but is also applicable for standard AC applications. The HVS-COMPACT serie contains all hydronic components which normally are located in the transformer box. The hydronic components are installed between the two coils (see picture) therefore the COMPACT version provides the same dimensions as the condensing unit of the SPLIT version does. Water connections on the rear side of the unit (see picture). Water piping max. distance app. 150 m* Capacity controlled chiller max. 150 m Fan coil unit (or any other kind of water coil) Leaving water temperature down to -5 C possible * Max. possible length depends on fan coil unit pressure drops and requested water flow rate.

Thanks to this innovative technology our products reach many advantages for our customers. Energy saving up to 35% compared conventional chillers.

5 System Diagram Split version HVS Digital is the latest generation of YORK s Air Conditioners for cooling and heating. These units use the Digital Scroll compressor technology that allows to adequate the capacity to the cooling or heating load. Thanks to this innovative technology our products reach many advantages for our customers. Energy saving up to 35% compared conventional chillers. High comfort because of the unit is capable to adjust the water outlet temperature in a ±0,5 C, thereby it is possible for the users enjoy always a comfortable ambient temperature. Absence of Electromagnetic Interference, compared a variable speed compressor, making the system easy and less sensitve. High reliability, as there is not necessary to use complicates electronic devices to get the right capacity. Not necessary to use buffer tank, thanks to the modulation control Not necessary to use glycol, as it is possible to use an intermediate transformer box as a remote evaporator. And many other advantages that you can discover by yourself using HVS units. DX piping (R407C), distance max. 20 m (i.e. total piping max. 40 m) Capacity controlled chiller Transformer box 20 m max. 150 m 5 m Max. height difference between condensing unit and transformer box: 5 m Water piping max. distance app. 150 m* (i.e. total piping length between Transformer box and furthest Fan coil unit max. 300m*) External heating system (Leaving water temperature max. 50 C) optional Fan coil unit (or any other kind of water coil) Leaving water temperature down to -5 C possible * Max. possible length depends on fan coil unit pressure drops and requested water flow rate.
